Filter by:Fluid expansion during cardiocirculatory insufficiency was helped by cardiac output monitoring. However, the goal of fluid expansion was to increase the oxygen delivery, which consider cardiac output, but also Haemoglobin which decrease during a fluid challenge. The maximalization of cardiac output could decrease the oxygen delivery if the haemodilution was too wide. The aim of this study was to describe the oxygen delivery during a fluid expansion conducted for cardiac output maximalization, following actual guidelines.
Preoperative fasting can evoke a hypovolemia which may cause a hemodynamic instability during introduction of anesthesia. The purpose of this study is to test the hypothesis that a defined preoperative volume substitution compared to standard procedure will result in a reduced incidence of hemodynamic instabilities during introduction of anesthesia in elective surgery patients.
The need for fluid resuscitation (FR) in ICU patients with acute respiratory distress syndrome (ARDS) is common. Indeed, relative or absolute hypovolemia is a common phenomenon that the intensivist must recognize early and treat promptly. Fluid challenge may have adverse side effects associated with fluid administration. The diffusion within the interstitial space may favor edema formation and cause cardiac dysfunction by volume overload. Edema formation is global and may specifically alter pulmonary alveolar epithelial integrity, leading to enhanced alveolar edema and impaired gas exchange. Currently, two types of fluids are frequently used, crystalloids and colloids. Among colloids and compared to crystalloids, albumin has the theoretical advantage of causing greater volume expansion. We hypothesized that a fluid resuscitation therapy with albumin generates less pulmonary edema than a fluid resuscitation therapy with crystalloids. The aim of our study is to compare alveolar fluid clearance, as a marker of alveolar edema fluid resorption, in 2 groups of patients: those treated with albumin and those treated with crystalloid.
There is growing evidence that the risk of postoperative complications can be decreased by optimizing the amount and type of infusion fluids given during surgery, steered by goal-directed therapy based on flow-related hemodynamic parameters, particularly in high-risk patients. This study is undertaken subsequently to test the hypothesis that the intraoperative goal-directed strategy based on FloTrac/Vigileo, a minimally invasive monitor, can partially prevented postoperative complications and shorten hospital stay in the elderly high-risk patients undergoing total hip replacement with continuous spinal anaesthesia .
The purpose of this study is to understand and document measurements in heart stroke volume (the volume or amount of blood pumped per heart beat) and cardiac output (the volume or amount of blood pumped by your heart per minute) during a passive leg raise maneuver (elevation of the legs), and to determine if these measurements can predict changes in the same as a result of fluid or blood product administration.
The purpose of this study is to verify any existing relationship between urinary parameters (such as excretion of sodium, chlorine, urinary partial CO2 pressure [PuCO2]) and general volemic indicators (such as PiCCO, ScvO2, O2 delivery) during liver transplant.
The purpose of this study is to verify any existing relationship between mixed oxygen saturation (from central venous catheter) and urinary sodium, potassium, chloride in determining the volemic state and renal perfusion of patients undergoing major surgical interventions.
Monitoring could secure management for patient but stay invasive. The purpose of this study was to compare,after cardiac surgery, the cardiac output measurement between transpulmonary thermodilution(reference method) and digital photoplethysmography (non invasive) for absolute value and dynamics changes before and after fluid expansion for patients with indication of fluid challenge.
This is a randomized, controlled, open-label clinical trial aimed to evaluate the Safety of Kedbumin 25% Compared to Normal Saline Solution in the Treatment of Post-Surgical Hypovolemia in Pediatric Patients Undergoing Major Elective Surgery. It will be conducted at approximately 5 surgical and pediatric intensive care units (SICU/NICU/PICU) in the US, over a period of 19 months, and the study population will consist of at least 60 male and female pediatric subjects between 0 days and 12 years of age, undergoing cardiac, abdominal, orthopedic or transplant surgery with an approximately equal number of subjects (n=10 to 25) in three of the four age groups: (29 days to 23 months), (2 to 5 years 11 months) and (6 years to 12 years) cohorts.
The aim of volume replacement is to compensate a reduction in the intravascular volume e.g. during surgery and to counteract hypovolemia in order to maintain hemodynamics and vital functions. To achieve this, different plasma substitutes are available: Albumin, dextran, hydroxyethylstarches and gelatine. The aim of this study is to demonstrate that acid-base alterations during elective abdominal surgery can be reduced by the use of a new gelatine solution.
